mostruosi.... davvero!

[[XC] Synthetickiller]

Thank you for the benches! :up:

[AMDforME]

FYI - There are a number of reports of problems specifically with the Samsung 840 model SSDs. I don't know the details but you might want to do some research before using these for important data files.

[Ourasi]

The only report I've read about, are some possible TRIM issues. Sweclockers have not been able to redeem fresh performance after writing 1.5TB of random continuos 4kb files, with only a format to trigger TRIM.. Silly way to torture a drive, and anand's torture on drivesize+overprovisoning did not have such issues..

[st0ned]

Now I just need to see 256GB benches to make up my mind between 128GB or 256GB :)

[Highendtoys]

And then your drives die. There are issues with the Pro's firmware. I'd wait till an update comes out.

I don't know all the details yet, but I wanted those interested in this drive to be aware of documented issues before they purchased, not after.

As far as Anandtech is concerned they and other prominent PC hardware review sites typically get hand picked and even sometimes tweaked products to review due to their large audience. On occasion they even get a new BIOS or firmware to fix issues, while consumers get stuck with the defective BIOS/firmware in shipping hardware. I've seen this before and Asus refused to provide the same BIOS to consumers that they provided to Anandtech. That's unscrupulous and unacceptable IMO. It may even constitute consumer fraud in many locales?

Many consumers fail to understand that few review sites are going to report issues before consumers confirm the problems. A sample of one by a review site should be taken with a large grain of salt be the review positive or negative. If I had a dollar for every bad mobo, GPU, SSD, etc. shipped, I'd be a very wealthy person. ;)

I received the drive with updated firmware, DXMO3B0Q.
The firmware that had problems was the previous DXMO2B0Q, which was provided in the samples sent to magazines for reviews.
For now, no problem for me. :up::up:

[AMDforME]

^^^ Cool. I hope your SSD is trouble free in operation.

It's insane that so many SSDs are rushed to market without proper validation. The fact that reviewers got Samsung 840 Pro drives with firmware defects supports my point about the rushed to market mentality. This has happened over and over and over with consumer grade SSDs from most of the popular SSD brands.

By contrast, Intel was very slow to bring a SF based drive to market. When they did--well, I have had my Intel 520 SSD since early this year. It came with firmware 400i and that is still the current firmware version. At this point I would actually like to see what a firmware update looks like just for the heck of it.

Now I just need to see 256GB benches to make up my mind between 128GB or 256GB :)If I wouldn't have reached the limit of 13 allowed attachments, I would be able to present some very good benchmark results done with my brandnew 256 GB Samsung 840 Pro, but you can not really compare them with those unrealistic ones, which were posted by nik58.
His tests were done with absolutely empty brandnew SSDs, whereas my Samsung SSD is a system drive with Windows 8 x64 and several applications (inclusive MS Office, Windows Defender etc.). Nevertheless my results are a little bit better than nik58 ones done with a single 128 GB Samsung 840 Pro SSD.

In case you haven't seen this review: http://www.servethehome.com/samsung-840-pro-ssd-256gb-benchmarks-review/

I've got my first 4-pack of 256GB Samsungs this week, will check them next week on an LSI controller.

[Brahmzy]

My 2 840 Pro 256s get here Tuesday. I'll post up some benches. Those 128s are rockin'!

Is it safe to say the 128s are pretty much on-par with the 256s?

If so, that is great, because I need 2 128s for 2 other systems.

Thanks a lot, you are the man ! Please report back about the results with LSI despite I don't have the kind of cash to go for a solution such as yours.

So, I've always done 128K stripes. I've noticed intel is now defaulting to 16K stripes.
Most folks still doing 128K stripes?

I used 128k stripe.
I have not tried other values.

This is the result of as ssd with OS and programs installed.
I saw the results of the raid 0 to 2x256, and I notice that the 128 are pretty good and essentially maintain performance :up::up:

It's great that you have not had issues with your SSD but many folks do. Those who don't have issues tend to believe that their model SSD is defect free but often the defects take awhile to show or show only with certain hardware combinations or applications. Some models have more issues than others. Firmware updates usually occur for major Bugs. You can still have issues like capacity loss, deactivated TRIM, etc. which may not be obvious for quite a while. Many folks didn't know that a certain series of SSDs all shipped with TRIM deactivated... ;)

Keep an eye on your SSD for changes in performance and capacity. This will be a clue that something is amiss.

[Highendtoys]

840 Pro is already old and slow for a handful of people.

[AMDforME]

840 Pro is already old and slow for a handful of people.

The 840 pro is actually intended to be a slower/cheaper SSD not the top of the line in benches. Most people can not tell the minute performance differences in SSD speed without running benches so it's usually best to buy the SSD that fits your budget and that has a good reliability and compatibility history. If you need the latest, greatest trick-of-the-week SSD or other PC component then you should expect to pay top price and be an unpaid beta tester.

[Brahmzy]

Huh?

[Highendtoys]

LOL - I was just really LOLing. The comment was bad enough but the name with the comment makes me lol for real.

Intel had/has the pull to get SF to come off their firmware code so they could re-write it together, from what I've been able to deduce. There was NO WAY Intel was gonna launch a problematic SF2200. Imo Intel is quite happy with their combination of high binned nand slathered with their 'secret sauce'. I think we MIGHT see a fw update if 5.0.5 lives up to expectations...ofc it'll take for ever to qualify per Intel's standards.

Ok...sorry for going off topic fellas.

I really want to see how the 840Ps perform after they have been dirtied up with few TBs then fill tested. Even tho the above benches were achieved by FOB drives, the 128 is still pretty damn impressive. As u can tell by my sig, I always keep an eye out for 'Best Bang for the Buck' candidates and 2 x 128GB 840 Pros in R0 may be the ticket.

Single Samsung 840 Pro 256 gb version, clean drive, no OS yet.

[Lu(ky]

Guys I noticed the 256gb models has a cache of 512MB Samsung LPDDR2 SDRAM and the 128gb or lower has 256MB Samsung LPDDR2 SDRAM would this make a huge difference in performance in a raid 0?

[Highendtoys]

That is page table cache and not user data cache. The larger drives need to map more data points.

[Zaxx]

Just now had my first peek at the 840 Pro 128GB price....youch! Damn near $200 at NewEgg. The 256gb pro is only ~$75 more. Looks like I'll be waiting (and hoping) for a xmas price war between the 840 Pros and the Vectors. Also wish SuperSSpeed would get with the program and list the 64GB SLCs and maybe come down a bit on the 128GB SLCs. Good chance I won't be pulling the trigger on a pair of drives for raid0 til after xmas...halfway tempted to just say the hell with it and get another 520 for $120.

Yeah I forgot to save for Black Friday, and Cyber Monday when things where cheap now everything goes up when I finally want to buy these drives...:shakes:
But I did find SuperBiiz has the 840 Pro 128gb for $139.99 with free shipping and another -$10.00 off coupon off the web, but I have to pay tax comes to $148.00 shipped..

[Zaxx]

Muuuch better pricing...let the SSD xmas price wars begin!!!


...damn that tax sucks.

[annaconda]

I think 840 Pro is the way to go. I saw earlier 128GB Pro was listed for $139 @ Gadgetar (http://gadgetar.com). It looks close to Black friday price. I might buy one!

[Zaxx]

It's gonna be 'no easy task' deciding when to pull the trigger and on what. This is crucial to my 'best bang for the buck' prime directive of sorts. Grrr...
Only thing that is for sure is that it'll be 2 x 120/128 (or 2 x 64 with SLC). Gotta wait it out a bit if I want to make a 'no regrets' choice as with my other components.

btw...lurve that case annaconda...and the cooling you have set up ofc.

Yer...seen that in my inbox today. It's decent but I'm waiting til they hit $99.99 + FS...give it another month or so I estimate.

[BigDisk]

The 840 non-pro is at 99$ today at newegg.ca with promo code CEMCXWTX74

Is there a huge difference between the pro and non pro variants?

[Alex-Ro]

Yeap,especially at 128 gb variants....

Got my 2 Samsung 840 Pro drives today and running them in Windows 8 RAID-0 setup on a Z68 Motherboard with modded OROM 11.6.0.1702 and IRST 11.7.0.1013. I would upload my test pics but forum keeps telling me that they are not a valid image file.

[felix_w]

Reduce image size or analysis and retry. If it doesn't work, use an image hosting service.

[Think]

Picked up 2 pro 256 using the Asus Fomula V board. Just wondering if everyone is using the onboard raid or shooting for a raid card.

[dja2k]

Here is my test results with 2 128GB Samsung 840 Pro SSD Drives running in Windows 8 RAID-0 on an ASUS Z68 Motherboard with modded OROM 11.6.0.1702 and IRST 11.7.0.1013

What do you think, the reading curves still look odd in some of those testings.

[Think]

nice dja2k. Anything I should know about when setting up the raid configuration ?

[dja2k]

nice dja2k. Anything I should know about when setting up the raid configuration ?
Well I haven't been able to update the firmware on these since I have it on Raid0 and don't want to break the Raid just to do a 30 second flash on each which would require a Windows install on single drive.

Don't forget to Enable Write Back Cashe on the IRST Software and Turn Off Windows write-cashe buffer under Device Manager on your Raid Drive. I also ran the Disk Optimizer on Windows 8 before I did the testing. Also if you haven't done so, try to look if there is a modded OROM bios for your board to enable TRIM.

Other than the weird spikes on two of the Tests, that's about I have to say, hope that helps.

Hmmm. Any tips guys? My 4k speeds are really lacking. Here are my 2x 128g 840 pros in raid 0 on on asrock x79 board. These are Windows 8 boot using 128 stripe.

Turn off ALL powersaving in bios, set high performance in powersettings in windows. install the new intel inf chipset drivers and intel RST from station-drivers.com. Enable writeback in Intel RST storagemanager. Then overclock the cpu :) Then you have 32-38MB/s 4k read :D

Updated bios on my asrock x79 extreme4-m to the 2.75 beta version found on station drivers. Updated RST to version 12. Enabled writeback in storage manager and...

Huge improvement. Still not quite happy with those 4k speeds though...should be a tad higher from everything I've seen.

[zer0patches]

I really like the 840 pro series, been running one in my work laptop for a couple months now and just finished upgrading my wifes computer to one today. =p

Although on my personal PC I have been running 4x OCZ 80gb Vertex 2's in R0 for quite a while now. Thinking it might be time to upgrade. =p

Note that rated read/write speeds are different for the 128gb / 256gb samsung models.
128gb is rated to 530/390 read/write, 97k read ops, 90k write ops.
256gb is rated to 540/520 read/write 100k read ops, 90k write ops.

Bench from my ocz raid array.
